If you enjoy diner tuna-melt sandwiches, you'll love the taste of this. To save time, use packaged frozen broccoli florets. Jarlsberg Swiss cheese works nicely in this casserole.

Ingredients Nutrition


  1. Preheat oven to 400 degrees Fahrenheit. In a large saucepot, cook pasta in boiling salted water for 5 minutes; add broccoli to pasta and cook another 5 minutes or until broccoli is tender and pasta is al dente. Drain well and return to saucepot; set aside.
  2. Meanwhile, in a 3-quart saucepan, melt butter or margarine over low heat. Stir in flour, salt, and pepper until blended and cook, stirring constantly, 1 minute. Gradually stir in milk; increase heat to medium-high and cook, stirring occasionally, until mixture thickens and boils. Boil 1 minute, stirring frequently. Remove saucepan from heat and stir in 1 cup of cheese until blended.
  3. Add cheese sauce and tuna to pasta and broccoli in saucepot; toss until evenly mixed. Transfer mixture to a 13"x9" glass baking dish. Arrange tomato slices on top, overlapping if necessary. Sprinkle with remaining 1/2 cup cheese.
  4. Cover baking dish with foil and bake 20 to 25 minutes or until hot and bubbly. Makes 6 main-dish servings.

Simple & tasty, but, in my case, the Swiss cheese seemed to overpower other flavors. I have other tuna casseroles I prefer, but this one is okay.

Delicious. I have made this recipe at least 3 times and it is so easy. A winner!

This casserole is yummy! I used the shell pasta. I especially liked the tomatoes on top w/ the melted cheese. (I think some diced tomatoes would go well in the casserole as well.) I recommend at least doubling the flour, because only 2 tbsp was not enough to thicken 4 cups of 2% milk for me. The family enjoyed this; we'll have it again. Thanx!
